Kernrechtsfrage
Whether the parties' cohabitation constituted a simple partnership from 1980 onward
Extrahierter Entscheid
Yes. The factual findings supported a common purpose and joint contribution, and the Federal Court would not reweigh evidence.
Extrahierte Begründung
The existence and starting date of a simple partnership are reviewed as a matter of law, but the factual findings on actual intent are binding absent exceptions. On those findings, it was not objectionable to infer that the partners subordinated their individual positions to a common economic purpose.
